Mission

Dah Mission is to build a sparkin machine. The idea is to creat a plume of sparks the rise into the air.

Basic Design

A previous design used a propane fed venturi to such spark-dust into a flame. The design was abandoned because the maximum flow rate of propane that you can get out of a 20lb propane tank is too low to sustain a high flow rate.

The thought now is to use air instead propane to feed the spark-dust into a flame.

Currently I'm investigating a design that uses a blower to propel air+spark-dust into a burner manifold. The spark dust is sucked through the blower and then into the manifold. In the manifold the air combines with propane and burns. The supper heated air ignites the spark-dust as it is propelled from the manifold.
